**** SECTION 3 - HAZARDS IDENTIFICATION ****

EMERGENCY OVERVIEW
Harmful by inhalation and if swallowed. Contact with combustible
material may cause fire.

Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. May be harmful if absorbed through the skin.
Ingestion:
Harmful if swallowed. May cause kidney damage. Ingestion of nitrate
containing compounds can lead to methemoglobinemia. The barium ion
is a muscle poison causing stimulation and then paralysis. Initial
symptoms are gastrointestinal, including nausea, vomiting, colic,
and diarrhea, followed by myocardial and general muscular
stimulation with tingling in the extremities. The barium ion is a
muscle poison causing stimulation and then paralysis. Initial
symptoms are gastrointestinal, including nausea, vomiting, colic,
and diarrhea, followed by myocardial and general muscular
stimulation with tingling in the extremities. The barium ion is a
muscle poison causing stimulation and then paralysis. Initial
symptoms are gastrointestinal, including nausea, vomiting, colic,
and diarrhea, followed by myocardial and general muscular
stimulation with tingling in the extremities.
Inhalation:
Harmful if inhaled. Causes respiratory tract irritation. Inhalation
at high concentrations may cause CNS depression and asphixiation.
Chronic:
May cause kidney damage. May cause kidney damage.

**** SECTION 4 - FIRST AID MEASURES ****

Eyes:
Flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Flush skin with plenty of water for at least 15 minutes while
removing contaminated clothing and shoes. Get medical aid if
irritation develops or persists.
Ingestion:
Call a poison control center. If swallowed, do not induce vomiting
unless directed to do so by medical personnel. Never give anything by
mouth to an unconscious person. Get medical aid.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid.
Notes to Physician:
For methemoglobinemia, administer oxygen alone or with Methylene
Blue depending on the methemoglobin concentration in the blood.
Institute cardiac monitoring for all significant ingestions of
soluble barium salts. Institute cardiac monitoring for all
significant ingestions of soluble barium salts.

**** SECTION 5 - FIRE FIGHTING MEASURES ****

General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Strong oxidizer. Contact with other material may
cause fire.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Contact
professional fire-fighters immediately. For small fires, do NOT use
dry chemicals, carbon dioxide, halon or foams. USE WATER ONLY. For
large fires, flood fire area with water from a distance.

**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Avoid runoff into storm sewers and ditches which lead to
waterways. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation. Do not use combustible materials such as paper
towels to clean up spill.

**** SECTION 7 - HANDLING and STORAGE ****

Handling:
Wash thoroughly after handling. Use with adequate ventilation.
Minimize dust generation and accumulation. Avoid contact with eyes,
skin, and clothing. Empty containers retain product residue, (liquid
and/or vapor), and can be dangerous. Keep container tightly closed.
Avoid contact with clothing and other combustible materials. Do not
get on skin or in eyes. Avoid ingestion and inhalation. Do not
pressurize, cut, weld, braze, solder, drill, grind, or expose empty
containers to heat, sparks or open flames.
Storage:
Keep away from heat, sparks, and flame. Do not store near
combustible materials. Store in a tightly closed container. Store in
a cool, dry, well-ventilated area away from incompatible substances.
Keep away from reducing agents.

**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****

Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate
ventilation to keep airborne concentrations low.
